The function V = √1.223w expresses the landing speed, V (in feet per second), as a function of gross weight, w (in pounds), of an aircraft. Write an equation that expresses the gross weight of an aircraft as a function of its landing speed

an equation that expresses the gross weight of an aircraft as a function of its landing speed will be given as follows:

V = √1.223w

we make w the subject of the equation, we start by dividing both squaring both sides:

V² = (√1.223w) ²

V²=1.223w

next we divide both sides by 1.223 to get:

V²/1.223=1.223w/1.223

w=V²/1.223

hence the answer will be w=V²/1.223
